Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters.
HIGH 7.5EPSS 0.43%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can eventually result in a stack overflow and panic. Remote attackers can craft packets which cause affected systems to panic. This affects any system where pf is configured to process traffic, independent of the configured ruleset.
